PUMP-OPERATING MECHANISM FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Aug. 16, 1910.

Application filed October 15, 1908. Serial No. 457,831.

To all whom it may concern:

Be it known that L'Lonrs A. MORGAN, a citizen of the United States, anda resident of Rlchmond, in the county of Wayne and State of Indiana,have invented a new and 7 Improved Pump-Operating Mechanism forAutomobiles, of which the following is a full, clear, and exactdescription.

My invention relates to certain improvements in pumps for use ininflating automobile tires or for general use, and adapted to beoperated from the engine of the automobile.

The object of the invention is to provide a simple and convenientmechanism which may be readily carried on the vehicle and which wheninserted beneath a single rear wheel thereof may be operated upon thestarting of the engine, so that any one of the other three wheels of thevehicle may be inflated, or the pump used for any other pur ose desired.

T e important advantages of my construction reside in the fact that itis portable; is operated from a single wheel of the machine; may bepacked in very small space, and is constructed to permit the vehicle tobe readily run up on to it or backed ofi.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures, and in which--- Figure 1 is aside elevation of the device constructed in accordance with myinvention, a portion thereof being broken away; Fig. 2 is a top planview thereof; and Fig. 3 is a side elevation of the frame in foldedposition for transportation.

The operating parts of my improved mechanism are mounted within asuitable frame 10, which need be a little Wider than the width of anautomobile tire and of not more than a foot in length. The oppositesides of the frame serve to support the operating parts of themechanism, and fastened to one end of the frame is a secondary frameserving as abridge whereby the vehicle wheel may readily travel up on tothe main frame. The operating parts include two rollers 11 and 12,adapted to support the vehicle wheel and be rotated upon the rotation ofthe latter. The sides of the main frame 10 are provided with two slots13,

extending from adjacent the upper edge downwardly toward the ends of theframe, and these slots serve as bearings for the spindles of the tworollers. The weight of the vehicle resting upon the rollers, tends tospread them apart and hold them in their proper positions, but upon theremoval of the vehicle wheel from the rollers, they may both be readilyremoved from the frameby raisin one end of each roller until it passesout of the slot. One of the rollers, as, for instance, the front roller12, serves merely as an idler and retains the vehicle wheel inengagement with the other roller, whereas the latter serves for theoperating of the pump.

The pump is carried by the frame and may be of any suitable formdesired. As shown, the pump barrel 14 is pivoted to one side of theframe, and the iston rod 15 is connected to a crank 16 at t e end of thespindle of the roller 11. The pump illustrated is a simple single-actingpump having a hose 17, through which compressed air may be delivered forinflating the tires of the machine.

The pump in itself constitutes no portion of the invention, and it isevident that a double-acting air pump or a water pump could be usedequally as well. If a water pump is used, it could serve for deliveringa stream of Water to wash the machine, or fill the radiator, or if anair pump is used, it could be employed for pneumatically cleaning thecushions, as well as for inflating the tires.

To enable the vehicle to easily reach a position with one rear wheelupon the rollers 11 and 12, I provide an auxiliary frame 18, having aninclined surface serving as a bridge to the top of the main frame. Theside walls19 of the auxiliary frame are triangular in form, and arespaced apart a distance slightly greater than the distance between theside walls of the main frame. The two frames are hinged together andpreferably in such a manner that the two may be brought together tooccupy the minimum space. As illustrated, the side members ofthe mainframe are provided with a slot 20, extending longitudinally thereof andparallel to the upper edge, and the auxlliary frame or bridge is securedto the main frame by a bolt 21, extending through the opposite sides 19of the auxiliary frame and through the slot 20. The main frameconstitutes a receptacle and is provided with be moved from the positionindicated in Fig.

- 1 to the position indicated in Fig. 3, to constitute a cover.

With the parts-in operative position, as shown in Fig. 1, and placed infront of one of the rear wheels of a motor vehicle, the vehicle may bedriven forward by its own power until one rear wheel reaches theposition indicated in Fig. 1. The vehicle will no longer advance, as thewheel resting upon my improved device may freely rotate at twice itsformer speed, while the other rear wheel remains stationary due to thepresence of the differential gearing employed in all automobiles.

All of the power of the engine will be utilized in operating the pump,and the latter may be used for any purpose desired, as, for instance,inflating the tires, cleaning the cushions, or pumping water.

In order to facilitate the backing of the vehicle off the frame, therear roller 11 is preferably provided with a ratchet wheel 23, havingengagement with a pivoted dog 24, supported on the inner side of themain frame. This permits the roller to be rotated in one direction butprevents its rotation in the opposite direction. When it is desired toback the vehicle off the device, the reverse gearing is automaticallythrown in operation and the rotation of the vehicle wheel in theopposite direction permits it to readily pass over the rear roller anddown the inclined bridge.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

A device of theclass described, comprising a main frame in the formof a receptacle or container, a pump supported thereby, a rollersupported by said frame and operatively connected to said pump andadapted to be operated by a motor vehicle wheel, and a cover for saidreceptacle, adapted to serve also as a bridge to said receptacle.
